--- Comment #2 from Martin Sebor <msebor at gcc dot gnu.org> ---
I should add that issuing a warning when an attempt is detected to modify a
const object (or subobject) as requested in pr90404 should help detect changes,
resulting from the optimization, to the behavior of code that deliberately
violates the restriction to modify constant subobjects.
